热管是一种高效的传热元件 ,被誉为热的“超导体”。针对大庆油田广泛使用的1 745MW火筒式加热炉 ,本文阐述了应用热管技术进行加热炉节能改造的方案、现场试验结果和改造推广情况。经测试 ,改造前后加热炉额定负荷下热效率提高了 7%以上 ,加热炉每天节气41 0m3。总共改造的 36台加热炉每年将节约天然气 560万m3节能效果显著 ,因而应用热管技术改造加热炉的方式具有推广价值 Heat pipe is an efficient heat transfer element, known as the hot “superconductor.” In view of the widely used 1 745MW torch heating furnace in Daqing Oilfield, this paper describes the scheme of heating furnace energy saving retrofit using heat pipe technology, the field test results and the promotion and promotion. After testing, before and after the transformation of the furnace rated load thermal efficiency increased by more than 7%, the heating furnace daily 41 0m3. A total of 36 rebuilt furnaces will save 5.6 million m3 of natural gas every year, resulting in significant energy savings. Therefore, the application of heat pipe technology to rebuild furnaces has the promotion value
